PRINTING MECHANISM FOR TYPEWRITING MACHINES.

Application filed January 15, 1527. Serial No. 161,400.

This invention relates to a printing mechanism for typewriting machinesand has for its object to provide, in a manner as hereinafter set forth,a printing mechanism for use in connection with typewriting.machines ofthe Hammond or similar makes for writing music and music signs.

Briefly described the invention relates to that form of typewritingmachine in which the printing is done by hammers and type carryingshuttles, the paper and ribbon be-. ing interposed between those partsto receive the impression on the actuation of the hammer which coactswith the shuttle. More par ticularly the invention relates in theincorporation of type in the form of music signs on the shuttles nowemployed in the Hammond and like forms of typewriting machines, and withthe shuttle carrying solely all the signs employed in writing of musicor a music score, thereby making possible the writing of music when ashuttle and hammer, in accordance with this invention, cooperate withrespect to each other.

The shuttles at present employed in the Hammond make of 'typewritingmachines contain three rows of type of thirty characters each, ninety inall. In accordance with this invention, there isto be employed insteadof the type now used on the shuttle, the music signs in a set of thirtyextending in a single row on the shuttle. Such arrange ment will permitthe notes and their stems to be equal in length to the width of theshuttle, and thus sufliciently large in relation to the other of themusic characters. Such other signs as rests and accidentals, which donot require to be as large as notes, can be positioned on the shuttlewithout extending' over the whole width thereof.

In conjunction with what will be termed a music shuttle having a musicsign arrange ment, there is employed a large face hammer, different fromthose now employed in typewriting machines of the Hammond and likemakes. This hammer has a music face or head of the same length as thewidth of the shuttle, thus enabling the head in a single stroke to coverthe entire width of the shut-, tle. At present hammers employed in typewriting machines of the Hammond and like makes have hammer faces, suchas manifolding face, mimeograph or stencil face, regular face forordinary typing, and Braille face for writing the Braille system for theblind. 0n a majority of machines, except special built ones for theblind, etc., there are three hammer faces employed and contained on thehammer which is of turret form. Instead of a fourth face there is atpresent a round knob which is of no use at all. At

this point on the hammer there will be arranged, in accordancewith thisinvention, the music face, which is of similar construction to theregular face, but of a different size as hereinbefo-re set forth.

Further objects of the invention are to provide, in a manner ashereinafter set forth, a printing mechanism for typewriters which issimple in its construction and arrangement, strong, durable, compact,thoroughly efficient in its use, conveniently installed in a typewritingmachine and comparatively inexpensive to manufacture.

With the foregoing, and other objects in view the invention consists ofthe novel construction, combination and arrangement of parts, ashereinafter more specifically de scribed, and illustrated in theaccompanying drawings wherein is shown an embodiment of the invention,but it is to. be understood that changes, variations and modificationscan be resorted to which fall within the scope of the claims hereuntoappended.

In the drawings wherein like, reference characters denote correspondingparts throughout the several views:

Figure 1 is a fragmentary view of a typewriter of the 'Hammond class, insection, showing the adaptation therewith of a printing mechanism inaccordance with this invent-i011.

Figure 2 is a plan, partly in section of a printing mechanism inaccordance with this invention and further illustrating more clearly theribbon shield which is constructed in a manner to provide for theoperation of the enlarged musicface of a hammer, in connection withtheshuttle.

Figure 3 is an elevation of the shuttle.

Figure 4a is an elevation of the ribbon shield.

Figure 5 is an elevation of the hammer showing the music face.

Referring to Figure 1 of the drawings A, B, (hand D indicate generally,respectively the anvil, shuttle, ribbon shield and hammer. The anvil Ais of the form employed in the Hammond typewriter machine and is ringshaped and slotted to receive the web 1 of the shuttle B. The ribbonshield C, hammer D as well as the shuttle l3,- differ as such elements,as shown, form parts of the well known Hammond typewriting machine andno claim for such elements is made in this application. The elementsreferred to collectively, by the reference character E, are employed tooperate the anvil A, shuttle B, shield C and hammer l). The inventionforming the subject matter of this application, relates solely to theshuttle B, shield C and hammer 3.

The shuttle B comprises body portion 2 of hard rubber made from a mastersteel die onwhich is engraved the characters forming the sign set andwhich are designed to be printed. The body portion 2 is formed with theweb 1 which extends through the slot in the anvil A, see Figure 1, andsaid body portion 2 is fixedly secured against the outer face and is ofmaterially less length than the circumference of the anvil. See Figure2. The body portion 2 of the shuttle B has its outer face providedthroughout with spaced music signs. The signs or characters 3, on theouter face of the body portion 2, are equal'in length and each is of alength corresponding substantially to the width of thebody'portion 2.The signs, characters or symbols 3 are few in number. The signs,characters or symbols indicated at 4 are of a size to occupy but onethird of the width of the body portion 2 and are arranged to providewhatmay be termed the upper row of the sign set. The signs, characters orsymbols indicated at 5 are of a size to occupy but two thirds of thewidth of the body portion 2, and are termed the lower row of the signset. The space occupied by the signs 5 normally would constitute the twolower rows of characters on the shuttles nowemployed.

The ribbon shield B is similar in construction to the shield employed intypewriting machines of the Hammond and like makes, but with thisexception that the slot 6, disposed centrally thereof, for the passageof the music face of the hammer to be presently referred to, is of alength slightly greater than the width of the sign set or in other wordsof a length equal to the width of the body portion 2. There is no needto specifically describe the shield G, as itis constructed similar tothe shield now generally employed in typewriting machines of the typereferred to, other than the setting up of the part 6 of a length toprovide the passage of the enlarged music face of the hammer.

The hammer D is of the turret formand neeae'm it provided with carbonface 7, a stencil face 8, a regular face 9 and a music face 10, which istwice as long as the other faces and projects above the base of thehammer equally as far as it is secured on such base, thus makingitdoublyas long as the other faces. The reason for this double sized music faceis to permit the production of notes with their stems attached, as wellas the E and F clef, in the correct proportion they bear to the othermusic signs. By striking the keys of'the machine without depressing,either the capital or figure keys, the cha 'acters of the upper row ofthe shuttle, indicated at a, will be written. By depressing the figurelrey the characters 3 and 5 can be w itten. This is made possible by theuse of the double size music face, used in conjunction with the signsplaced on the shuttle as illustrated.

The hammer D is constructed in a manner similar to hammers employed intypewriting machines of the make referred to, with this exception ofproviding the hammer with the elongated music face.

It is thought the many advantages of a printing mechanism'in accordancewith this invention for use in connection with typewrit-ing machines forprinting music signs can be readily understood, and although thepreferred embodiment of the invention isas illustrated and described,yet it is to be understood that changes, variations and modificationscanbe resorted to which fall within the scope of the invention asclaimed.

What I claim is:

1; In a printing mechanism for typewriting machines for typing music ashuttle operating on a vertical axis and including a body portionprovided on its outer face with a set of musical characters, certain ofthe characters of said set of a length substantially equal to the widthof said body portion and the remaining characters of said set arrangedin a pair of superposed rows extending lengthwise of the body portionfrom the first mentionedcharacters.
